application md February 1o, 1911. serial No. 607.738.

To all whom it may concern:

Be it known that I, WILLARD Iavmo TWOMBLY, a citizen of the 'UnitedStates, residing in the borough of Manhattan, 1n the city, county, andState of New York,

`have invented new and useful Improvements in Means to Drive Fans ofMotor-Vehicles,

of which the following is a specification.

' This invention relates to motor vehicles in which the motor is adaptedto be quickly placed iny position in and removed from the vehicle framefrom the front thereof, and is cooled by means of water circulatingVthrough a suitable jacket around the motor A and cooled by passingthrough a suitable cooler, such asia cellular radiator, a rotary l fandrawing a current of air through the cells of the cooler to materiallyaid m the cooling of the water, and itis the object of thev invention toprovide van improved method of and means to drive the fan.

v In carrying out my invention I rotativel mount the fan with the axisof its sha t parallel with the axis of the motor, and mount on saidshaft a drive wheel to rotate therewith 4and, have sliding movementthereon, and with which the fly wheel of the motor is thrown intofrictional engagement to operatively couple said wheels as the `motor 1splaced 1n the frame, whereby-to drive the wheel and fan from the drivewheel of the motor, means being rovided ing a part of thisspecification, Fi

'afplan View of the forward end of t e frame o a motor vehicle chassiswith a motor.

whereby to maintain the wheel in 'ctional contact with said fly-Wheel.

In the drawings accompanu 'ng and formre'l is y mounted thereinillustrating my improved method of and means to drive the fan. Fig. 2 isadetail side elevation, partly in section, to illustrate the relation ofthe fan i a drive-wheel to the fly-wheel; and Fig. 3 is an Aenlargedsectional side elevation of the fan-drive wheel, and the manner ofmounting the same on the fan-shaft. f

Similar characters of reference designate like arts throughout thedifferent views of the rawi'ngs.

In the present instance I have sho'wn my improved fan drive inconnection with a motor mounted in the frame of the chassis of a motorvehicle, the said frame comprising a pair of parallel side bars 1, 2connected in any suitable manner. A supplemental motor carrying frame,in the form of a pair of tracks 3, 4 parallel with the side bars 1, 2 isfixed to the frame. The motor 5 is supported on `said supplemental frameby means of rollers or wheelsl 6 rotatively mounted on the end of hangerarms 7 projecting laterally from the frame of the motor, the saidrollers permitting of the rolling of the motor into and out of thechassis frame from the front thereof. The motor is retained in the frameby a bar 8 extending transversely of and releasably connected to theframe bars, the said bar having a flange portion 9 to engage over theforward part of the motor frame to hold the latter firmly on thesupplemental frame. Pins 10 on the tracks 3, 4 engage in slots in lugs11 fixed to the motor frame, the said pins not only limit the inwardmovement of the motor, but also serve to hold the same firmly down ontothe tracks. To the power or crank shaft of the motor is fixed a flywheel22 the periphery of which is beveled, as at 23.

A water cooler (designated in a general way by C) of the cellular type,extends transversely of the frame and is fixed to the side bars 1, 2 inthe rear of the motor. A circulation of' the water is maintained througha jacket around the motor and said cooler by means of suitable pipes orducts 12, 13 connected to and leading from and to the motor and cooler,said pipes having automatic and flexible couplings therein 14, 15,vwhich may be in the form of slip joints, so that when the motor isrolled into the chassis frame it will be automatically coupled up withthe water cooler.

A shaft 16 is journaled in suitable journal wheel 22, is mounted on thefan-shaft 16 in `front of the water cooler, vsaid wheel rotatingy withthe fan shaft'and having longitudinal sliding movement thereon.Themclination of the bevel on the wheel 24 is opposite to theinclination ofthe bevel 23 on the fly wheel. To permit of the wheel 24to slide along the fan-shaft, said shaft is provided with a spline orkey 25 engaging in a vkey-wayin the hub of the wheel. The wheel ismaintained in frictional contact with the ily wheelyb'y means of atensionV spring 26 coiled about the fan shaft and confined between thehub of the wheel' and a washer 27 abutting against a cotter pin 28 xedin the fan shaft. The frictional contacting surfaces'of the wheel 24:and the bevel 23 on the fly-wheel may be provided with a suitablefriction material.

As already stated the Amotor is adapted to be pushed into and drawn outfrom the front of the chassis frame. When the motor is drawn out thefly-wheel will readily pull away from the wheel 24, and when the motoris again placed in the frame the fan will be automatically coupled inoperative relation with the'fly-wheel of the motor b v the bevel 23abutting against the cone whee Variations may be resorted to within thescope of my invention. 4

Having thus describedy my invention, I claim: 1
